Markets we serve
Food and BeveragesWe understand that the food and beverages industry manage
large volumes of products throughout their processes, and
that maintaining their quality and cleanliness is paramount. Our
extensive product range can be utilized for all areas of the food
and beverages market. Sterile conditions in a manufacturing
environment improve products longevity, ensure consistent
quality and reduce the need for preservatives in the final product.
Our expertise covers an extensive range of sector-focused
applications, such as edible oil, beet and cane sugar, artificial
sweeteners, cheese brine, cocoa butter and gelatine, within
the food and beverages sectors.
Mineral Processing – Molten SulphurImpurities have a significant negative impact on the efficient
production of sulphuric acid and operations across the world
need to ensure their filtration processes are designed to minimise
contamination and ensure the lowest cost of ownership.
Amafilter® has extensive expertise in the molten sulphur sector
of the sulphuric acid industry, having designed and supplied
pressure leaf filter systems across the globe assisting customers
to optimise their molten sulphur total filtration process.
BiofuelsBiofuel production presents unique filtration challenges. The
quality of incoming feedstock used in the production of biodiesel
can vary extensively. Converting inconsistent feedstock to high
quality, pure, renewable fuels that meet ASTM standards requires
extensive filtration expertise and appropriate technologies.
Amafilter® can carry out a complete analysis of your plant’s
processes and recommend the correct filtration and separations
technologies to meet the product quality you require.
Pressure Leaf Filter Systems
Amafilter® vertical and horizontal pressure leaf filter systems
The Amafilter® pressure leaf filter systems are designed to
maximise the filtration surface area of the filter leaves and
offer optimal bulk filration in the smallest footprint.
The pressure leaf filter systems produce high filtrate clarity.
Different types of filter aids can be used in our pressure leaf
filters to improve filtrate quality.
Selecting the correct equipment for your liquid filtration process is critical in ensuring your manufacturing facility operates efficiently, safely and productively.Our experienced engineers work closely with our customers to design complete filtration solutions to meet their specific requirements.
FEATURES & BENEFITS
• Proven technology
• The pressure leaf filter is a closed filtration system
which ensures safety of use.
• Easy access to the filter leaves for removal of the cake
• It is fully automated, making it safer and requiring
limited maintenance, hence lowering operational
costs.
• The regeneration time between the filtration cycles
is short, lowering operating costs as the filter can
filtrate for longer periods without disruptions. This
also delivers greater production capacity.
• Filter leaves are easy to clean.
• The pressure leaf filter system has no rotating
parts, keeping maintenance to a minimum.
• Reinforced filter leaves, longer lifetime
• Special self-sealing cover gasket. The gasket can be
re-used and does not need to be replaced after every
opening of the filter system cover. The gasket comes
with special self-sealing properties to ensure a perfect
sealing solution and promoting maximum safety.
• All pressure leaf filter systems can be made with
a heating jacket in order to maintain elevated
process temperatures. This is specifically required
to avoid cooling down of the suspension in
instances where this is not permitted during the
filtration process.
• Maximise your liquid filtration process
• Achieve optimal efficiency
• Deliver product quality
• Reduce maintenance costs
• Ensure safety at work
Working together to deliver
your filtration efficiencies
Pressure Leaf Filter Systems Options
Retractable shell with a lower support frame: The bundle doesn't move here, the shell is supported by rails and moves over the bundle.
Retractable shell with an overhead suspension frame: The bundle doesn't move, the shell hangs from a support structure and moves over the bundle.
Retractable bundle: The shell doesn't move; the bundle with filter leaves moves in and out of the shell.
HORIZONTAL PRESSURE LEAF FILTER SYSTEMSThe horizontal pressure leaf filter system is available in larger
sizes than the vertical pressure leaf filter system and has a
higher dirt capacity. This system can also be delivered as
tandem units maximising floor space, as two filters can be
fitted in one overhead frame.
Whilst the cake is being discharged, the horizontal pressure leaf
filter systems are fully opened which allows easier and quicker
maintenance or inspection.
VERTICAL PRESSURE LEAF FILTER SYSTEMSThe Versis® vertical pressure filter systems range only requires
a small footprint.

Dry Cake DischargePressure leaf filter systems with dry cake discharge are used
in a number of applications such as the filtration of sugar,
cocoa or edible oils, for the removal of activated carbon,
molten sulphur filtration or catalyst recovery. These systems
produce minimal product waste and for some applications
the residual product content in the filter cake can be reduced
down to approximately 35%. When the cake is the desired
product instead of the liquid and the cake is required to be as
pure as possible then washing of the filter cake is an option.
The filter cake is normally dried with compressed air, inert gas
or steam before the discharge.
Vertical pressure leaf filters only:
The filter cake is discharged by a pneumatic vibrator through
a butterfly valve located at the bottom of the filter which has
been specifically designed for easy cake discharge.
Wet Cake DischargePressure leaf filter systems with wet cake discharge are
perfectly suitable for applications where:
- the cake formation is too low for dry discharge
- the disposal is cheap (regeneration for wet discharge is
shorter)
- the cake/slurry needs to be transportable via a pump.
Special oscillating high impact jet headers sluice the filter cake
from the filter leaves. Filter cloth with low micron ratings can
be used for wet discharge. This ensures clear filtrate from the
start. The cake is sluiced through the discharge outlet.
Cake DischargeIn a horizontal pressure leaf filter system the complete set
of filter leaves can be moved outside the filter tank with an
electric or an hydraulic system before cake discharge.
Whilst the cake is being discharged, the horizontal pressure
leaf filter system is fully opened. This allows to:
• easily assess the condition of the cake
• ensure that the cake is fully released from the filter leaves
• check the condition of the pressure filter leaves after cake
discharge
Cake BreakersAmafilter® cake breakers assist the separation and discharge
of compacted cake on a pressure filter leaf by dividing the
cake into smaller segments. Cake breakers are ideal as a
cost effective mechanical device to assist with repeated cake
separation and discharge.
Filtration solutions for dry and wet cake discharge
PerformanceFilter leaves are the most important component of every pressure
leaf filter and replacing old or damaged leaves with new or
rescreened filter leaves will result in an immediate improvement
of the overall performance of the filter system.
Amafilter® filter leaves consist of five layers (ply) of stainless steel
wire mesh and are measured to a high degree of accuracy,
which increases system productivity and filtration efficiency.
ReliabilityAmafilter® filter leaves are manufactured, as a standard,
from stainless steel 316L due to its mechanical properties,
making them highly resistant to stress corrosion, variances in
temperature and extreme pressure changes.
Other alloy materials are available for particularly challenging
applications. The design, technology and high craftmanship
involved in the production of our filter leaves results in less
downtime for maintenance, increased productivity and
extension of the filter leaves life span.
The Amafilter® Versis® vertical pressure leaf system range and the Amafilter® horizontal pressure leaf filter systems range include an extensive choice of filter leaves designs to suit a variety of market sectors, including food and beverages, chemical and sulphur. The quality and condition of filter leaves can have a significant impact, not only on the productivity of the filtration system but also on its ability to achieve a high performance standard.

horizontal pressure leaf filters
• Stainless steel 304(L), 316(L), 904L or super duplex.
